Hello all

After checking the ejected pellets beneath roosts in constant use by POs over a 
long period of time, it was apparent that their main source of food was 
arboreal mammals. This all changed following a "reduction" burn over the 
foraging area when the diet changed to birds such as Pied Currawongs, Crimson 
Rosellas, Eastern Rosellas, Rainbow Lorikeets readily identifiable from 
regurgitated feathers or body parts such as beaks or feet . The ultimate 
demonstration of the change of diet was finding the PO clutching the body of a 
Superb Lyrebird. This was  probably the female which had successfully raised a 
chick each year for the past five years at least. It could not be found 
In about seven years of intermittent watching POs in this particular sandstone 
gully, I commonly found that the Ringtail Possum was the normal prey despite 
the fact that the site was within a couple of k's of the Gordon flying fox 
colony. Indeed I only once observed a flying fox used as food by a PO.
